Hi Wojtek and Robert, thanks for your replies. I'll try the patch in the evening and let you know if it fixes the problem on my side.
Robert, the restricion on the values 1, 2, 3 or 4 that you mention is related to ES profile only, or even to openGL 3.x and 4.x ?? That might be an issue to address when reviewing the different plugins.
